Summary

The purpose of this issue is to provide a way to track the status of the work necessary to ship v.4.0 of Ember.js

The list of issues should be updated to include links to individual issues as they are created. The individual issues should contain more details for each item on this list.

As a reminder: Major versions of Ember do not ship new features- instead, major versions remove previously deprecated features. To read more about Ember's philosophy regarding editions, please see https://emberjs.com/editions/.

Issues

• blocking Remove deprecated features (See Deprecation Cleanup for 4.0 #19617 for open tasks) (includes IE11 removals)
• Tracking for Remove jQuery by Default - Done from the Ember 4.0 perspective.
• 🔒 Ember.assign deprecation implementation Add deprecation warning to Ember.assign #19649
• blocking Deprecation guide for Ember.assign
• 🔒 Ember auto location deprecation implementation Deprecate auto location #19510 - we got this in targeting 4.1
• non-blocking for 4.0 🔒 Deprecation guide for auto Deprecate auto-location ember-learn/deprecation-app#882
• non-blocking: Remove classic examples from API docs
• blocking Make sure we aren't showing deprecated methods in the guides - mostly done except willTransition/didTransition
• blocking Update the optional features guide - has a PR
• blocking Update the Octane upgrade guide - has a PR
• Land [BUGFIX beta] Replace assert.equal in blueprints with assert.strictEqual to appease eslint-plugin-qunit on generation #19825 otherwise newly generated files will error due to the newer version of eslint-plugin-qunit in the 4.0 new project blueprint
• New browser-support policy: One to drop IE11 from Ember Data CI.
• blocking New browser-support policy: Need a canonical place to publish supported browsers, and we need to have the list for 4.0 in hand. And write it into the blog post.
• blocking The implicit injection of the store, which is deprecated, was not deprecated in all cases. @igorT has seen an OSS codebase that broke on 4.0 upgrade because the case was missed. This should be addressed as a release bugfix improving the fidelity of the deprecation. Disable ilios partner test warp-drive-data/warp-drive#7744
